UNTTED STATES PATENT SAMUEL WALKER LEWIS, OF NEW YORK, N. Y., ASSIGNOR TO GEORGE E. GILOHRIST, OF MELROSE, MASSACHUSETTS.

RECEPTACLE FOR WATER-CLOSETS, URINALS, 840.

SPECIFICATION forming part of Letters Patent No. 643,604, dated February 13, 1906.

Application filed March 16, 1899.

To all whom, it may concern Be it known that I, SAMUEL WALKER LEWIS, aciti'zen of the United States, residing at New York, borough of Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Receptacles for Tater-Closets, Urinals, and SimilarPurposes, of which the followingis aspecification.

My invent-ion relates to what are known as jet water-closets and urinals of the class provided with a receiving hopper or bowl, a means of flushing the upper wall of said hopper, which may be a hollow perforated rim, as shown, or a simple fan-wash or otherwise to wet or spray said wall and which I term a rim-flushing means, and a trapped outlet from said hopper, into which one or more contracted streams or jets of water is discharged to eject the contents of said hopper, which jet-discharge I term the main jetflushing means, the object of my invention being to quicken, and thereby increase, the power of action, decrease the noise of flow in the hopper, and economize water. As in my previous patent, No. 509,319, of November, 21, 1893, I trap the main supply-conduit to both the rim and jet flushing means,compressing and discharging the air from the flush or, supply pipe into the trap beyond the hopperoutlet; but when the air is discharged wholly through the main jet-flushing means, as described in that patent, it has to be driven down throughout the entire length of bend and depth of seal of the jet-pipe, whereby owing to the extreme depth of seal it encounters a resistance which retards or causes the action to hesitate until the descending column of water compresses the air sufficiently to overcome the resistance and expel it suddenly with explosive force, sometimes defeating the object of noiseless action. Owing to that difficulty the" depths of seal in the hopper and jet-pipe must be limited, the tank or supply more elevated for increased power, or an outlet provided for the air; but by my new and simple arrangement of the main supply to both rim andjet flushing means in combination with an auxiliary jet-outlet, the discharge from which I term a relief-jet for the escape of air into the trap beyond the hop- Serial No. 709,375. (No model.)

per-outlet,I attain a much quicker action,can make the hopper with greater depth of seal, and obtain all the objects sought, as hereinafter described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view, in side elevation, of a closet provided with my improved arrangement of rim and jet supply and showing the location of the relief-jet outlet. Fig. 2 is a reverse external view of same, showing the return upward of the rim supply-pipe. Fig. 3 is a broken longitudinal external view, in side elevation, to show that the construction of rim and jet pipes may be modified. Fig. 4 is a broken cross-sectional view from front approximately on the line X X in Fig. 1.

The sameletters of reference are used to indicate identical parts in all the views.

A is the receptacle or hopper,with a flushing-rim O and sloping Wall contracting to its outlet at 1) into an up leg or trap B, which maintains the normal level of water in the hopper 'up to its point of overflow at b, as shown by dotted lines in Figs. 1 and 3 and also by dotted line W L in Figs. 1 and 4, the lower outlet edge of the hopper, as shown at b, forming the seal. In the example shown the trap B is provided with a down-leg G H, forming a -siphon; but this is not essential to my invention, as the trap may lead from its overflow b horizontally to a connection with the sewer system,as suggested by dotted lines 19 or otherwise.

E is my improved main supply -conduit leading down below the normal level of water, where it divides at f into two sub conduits or pipes preferably of the same depth of seal. The pipe 0, which I regard as the main conduit, leads, preferably, down under the bowl at c and up on the other side to the rim, as shown at 0 Fig. 2. The other subconduit e leads down in the usual manner to the main jet-flushing means at D and is provided at or below the level of seal 1), as indicated by the dotted line y y, with a small outlet-opening (1 for the relief-jet, which is pointed upward into the trap,as also shown at din Fig. 4.

If desired, the pipe 0 could lead to the jetoutlets and the pipe 6 could lead to the rimflushing means, thus reversing the position of the two bends c and D beneath the hopper, or, as the jet-pipe 0 turns inward and under at D, as shown in Fig. 3, the rim-pipe 0 can pass outside or over it and thence under the hopper, the modification being shown to illustrate adaptability to various changes all within the scope of my invention; but I prefer to keep the jet-pipe above the rim-pipe to enable the air-bubbles, which naturally follow the highest wall, to escape more readily through the relief-jet outlet at d. Furthermore, the rim-conduit 0 could be trapped to the desired depth and return up to the rim on the same side without passing under the hopper.

\Vhen used with a cistern and open flushpipe F, the relief-jet outlet should never be above the point of seal 1), as indicated by dotted lines y y, whereby the flush-pipe F will be trapped as deeply and securely as the hopper; but when connected directly to the supply and operated by a direct-pressure-flushing valve, such as a flushometer, whereby a solid column or supplyof water leads to the closet at E, the position of the relief-jet outlet maybe modified. In other words, with the main flushing pipe or conduit filled with water from the flushing-valve to the receptacle the location of the air-relief jet can be at any point or dispensed with entirely and upon opening said flushing-valve under the latter condition the discharge of water at the main jet flushing means is instantaneous; but owing to the greater distance from the entrance of the rim-pipe to its outlet at the rim the rimflushing means is secondary in its overflow action and much more noiseless than if the full force was exerted at the rim, as in the ordinary jet-closet or as described in my said Patent No. 509,319, in which the rimpipe is much shorter proportionally, leading only from the main jet to the rim, an advantage being gained by increase of the length of the rim-pipe below the water-line, as herein set forth. =Fl0ll1 this construction I get the following result in operation: hen the waterpressure is admitted to the main supply F E, the air therein is compressed, and having only to be forced down to the relief-outlet d the resistance is slight, it yields quickly, the main jet action is instantaneous, while the pressure extending to the pipe 0 causes the water to rise through the rim-pipe c and gently overflow down the interior wall of the hopper A, as indicated by arrows in Fig. 1, the jet action being actually in full force or play before the rim-wash begins, thus effecting a quick, smooth, and noiseless action with less water than heretofore, because the action is so prompt that it requires less water to start and operate it, and, furthermore, I am enabled to decrease very materially the total jet area, thereby giving more water to the rim, the jet-flushing means in this construction being auxiliary to the rim flushing means and merely used to facilitate action. Hence I have termed the rim-pipe the main supplyconduit and the jet-pipe a branch therefrom, and as provident use of water is becoming a factor in municipal and domestic economy the advantage of such result will be apparent.

The Patent No. 555,455, granted to me February 25, 1896, shows a main supply-pipe divided above the water-line into two separate trapped or Water-sealed conduits of unequal depths of seal, the conduit having least depth of seal leading to the jet-flushing means and the conduit having greatest depth of seal leading to the rim-flushing means, whereby any air in the main supply-pipe meeting less re sistance in the trap or seal of least depth will be discharged through the jet-flushing means without'noise at the rim. Furthermore, the jet-outlet in that closet is located at about the same depth or level of seal as the upper edge of the outlet from the receptacle. Hence a relief-jet is not necessary, as in my present invention, in which latter the jet-outlet is submerged to almost double the depth of the seal of the receptacle. Hence the value of the relief-jet, as hereinbefore described,which enables me to locate or submerge my powerjet as deeply as desired, and by dividing my main supply below the normal water-level I am enabled to have the same normal level of water in both pipes as in the receptacle or hopper.

It should be understood that one purpose of the invention is to provide means below the water-line of the main supply-conduit,

whereby the flow of water through it is caused I to be separated into two streams at the same time, one of which extends to the rim-flushing means and is retarded in its passage thereto and not throttled thereby, whereby it escapes into the bowl with little or no pressure and noise, and the other of which extends to the bottom of the bowl and provides a relatively-forcible jet-flushing means which begins to operate slightly in advance of the rimfiushing means. An advantage in the construction of the bowl also arises from this arrangement of passages in the conduit in that the partition in the conduit being relatively short can be more surely and perfectly formed in the process of molding and baking the bowl than if carried above the water-line of the conduit, which would necessitate the making of a partition of very considerable length and one that is very liable to injury in the manufacture of the bowl.

Having described my invention, I clain1 1. In a receptacle for water-closet or urinal or similar purposes, provided with a receivin g hopper-or bowl a trapped outlet therefrom a rim-flushing means and ajet-flushing means, the main conduit leading from the source of supply to the rim-flushing means forming a loop or trap beneath the normal surface level of the water in the bowl and the conduit leading to the jet-flushing means branching from said main or rim conduit at a point below said normal water-level and leading first to a relief-jet outlet for discharge of air into the trap and thence to the main jet-flushing means in the lower wall of the outlet-passage, substantially as and for the purpose specified.

2. In a receptacle for water-closet or urinal or similar purposes, provided with a receiving hopper or bowl a trapped outlet therefrom a rim-flushing means and a jet-flushing means, the main supply-conduit made integral with the hopper or bowl and divided above the level of seal into two branches one leading by a loop beneath said hopper and up to the rimflushing means and the other leading first to a relief-jet outlet and thence to the main jetflushing means discharging upward into the trap, whereby the air can escape through the relief-jet outlet and the action of the closet be quickened, substantially as and for the purpose specified. 7

3. In a receptacle for water-closet or urinal or similar purposes, composed of a receiving hopper or bowl in which the normal level of water is retained by a trapped outlet-passage therefrom and provided with a rim-flushing means and a jet-flushing means, the main supply-conduit leading from the source of Suppl to the rim-flushing means by a trapped loop below said normal water-level and the conduit leading to the jet flushing means branching from said main or rim conduit at a point below said normal water-level and above the level of the seal of the hopper and leading first to a relief-jet outlet located at or below said level of seal and thence to the main jet-flushin g means discharging from the hopper-outlet upward into the trap, substantially as and for the purpose described.

4. In a receptacle for water-closet or urinal or similar purposes, the combination of, the

hopper or bowl A provided with a suitable rim-wash and a trapped outlet-passage B, the main supply-conduit E c o 0 leading to the rim by a trap beneath the hopper, the jet conduit 6 branching from the main conduit at f below the normal water-level and leading to the relief-jet outlet located at or below the level of the seal of the hopper, and thence to the main jet-outlet at D discharging upward into the trap, all substantially as and for the purpose described.

5. In a receptacle for water-closet or similar purposes provided with a receiving hopper or bowl an upper flushing means therefor a trapped outlet therefrom to maintain a normal water-level in said receptacle and a jetfiushing means discharging into and through said trapped outlet, the combination of a flushing supply-conduit for said receptacle divided below said normal water-level and before reaching the jet-flushing means into two subconduits or branches, the shortest of which leads from the point of division to the jet-flushing means and the longest branch leads from said point of division to the rimfiushing means, the normal surface level of water in said conduits being the same as in the bowl, whereby owing to equal pressure at the point of division and greater length of rim-pipe from said point of division the overflow action at the rim follows the jet action and is rendered more gentle and noiseless.
